N1018-D-K-TVP-SP-XL

The N1018-D-K-TVP-SP-XL is a high-precision single-row cylindrical roller bearing engineered for the demanding conditions of machine tool main spindles. With its 90x140x24 mm dimensions, it is designed to accommodate high radial loads at extreme speeds. The "SP" designation signifies its tight manufacturing tolerances, ensuring superior running accuracy for high-quality machining operations. This bearing is the ideal choice for applications where radial stiffness and high-speed capability are critical performance factors.

This bearing incorporates several key design elements for superior operation. The tapered bore (K) allows for precise adjustment of internal clearance, enabling optimal setup for maximum rigidity and running accuracy. Its robust glass fiber reinforced polyamide cage (TVP) is not only lightweight but also provides excellent guidance for the rollers, ensuring low friction and cool operation even at high RPMs. As part of the XL series, it offers enhanced load ratings and an extended operational lifespan.

The N1018-D-K-TVP-SP-XL is specifically designed as a non-locating bearing, expertly managing high radial forces while allowing for axial displacement of the shaft relative to the housing. This feature is essential for preventing stress from thermal expansion in high-speed applications. The combination of its super-precision build, advanced cage material, and optimized internal design makes it a highly reliable component for improving the performance and longevity of sophisticated machinery.
